The module requires that account passwords be consistent across all SLD servers

This is the last major code addition from Scott

Original description:

"The module requires that the account password is the same across all SLD servers.

Added a command line script that allows the user to specify the current account password for a server and change it to something else by sending the EPP registry a newPW command on login.

Example usage: ./zacr-cli changepassword org.za "
